Kinda like a loud grind/clunk? Mine's done that since it was new...doesn't always do it, just every now and then...I've wondered the same thing myself. Since I could never repeat it on a consistent basis, I never bothered taking it in.

Mine does that too. I think it is the fan belt slipping when the clutch engages, but I haven't opened the hood to see since it did it when I test drove a few trucks while looking for mine.

My AC was low on gas when i bought it last october. i finally got around to blasting some in the other day and the ac blew COOOLDDDD. the next day i went out lit up the monster turned on the ac and i thought i tore something up when mine made the noise, scared the crap out of me 
. the beast is runnin good the ac is blowin cold and the noise has occured at least three more times with varying degrees of god-awfulness. its kindof wierd how several of us has noticed this noise at the same time of year. hopefully someone that knows why will stumble our posts and educate us.

Mine does it every-so-often as well....only on the first time I turn it on for the day. I`m not sure what it is , and like others , I`ve not bothered having it looked at because it won`t do it ALL the time , and I know it WON`T do it for the dealer....or they`ll tell me it`s caused by the lift/programmer/tires/etc...

Sounds like the system is over charged to me!
Take it to a shop with good recovery equipment and see how much comes out and then put the proper amount back in.
More is not better in air conditioning.
In a nut shell you cant compress a liquid and when a system is over charged that is what the compressor is trying to do and of course will make a lot of noise.
Not normal and will fail in time
